Description

Analysis of the available experimental data obtained for the reactions , and at the nucleus, shows that almost all excited energy levels up to 2.0 MeV may be assumed to be uncovered [1]. The experimental data indicate the presence of a deviation from the Alaga rule. In particular, forbidden transitions from states of the band are observed.
In [2, 3], within the framework of the phenomenological model [4], which takes into account the Coriolis mixing of the states of the rotational bands, the low-lying states of the nucleus were studied. The energies, wave functions, and electrical characteristics of the states of the rotational bands were calculated. The reasons leading to the non-adiabatic effects, which manifest themselves in energies, wave functions of states, and ratios of transitions from vibrational states, are shown.
In the present paper we continue the study of the properties of the rotational states of the nucleus . We have calculated the reduced probabilities of transitions, using the wave functions obtained in [2]. The effect of rotation on the magnetic characteristics of excited states is studied. The calculated values of the probabilities of transitions from the states of the and bands are listed in the table and compared with the available experimental data.
